Merging KVM QEMU changes upstream

[Anthony Liguori <aliguori-r/Jw6+rmf7HQT0dZR+AlfA@public.gmane.org>]

Hi,

As most probably know, the KVM project has been maintaining a QEMU tree 
for some time now.  Beyond support for the KVM kernel interface, the 
tree also contains a number of useful features like live migration, 
virtio, and extboot.  Some of these things have been posted to 
qemu-devel already but were not included.

I would like to work on merging the KVM changes into upstream QEMU but 
before I started that work, I wanted to get a read on how difficult it 
would be.  A lot of these things were designed specifically for KVM on 
x86.  Only now are other architectures starting to be considered.  
Certainly, cross-architecture emulation hasn't really been considered.

I wouldn't expect anything to be merged that caused a regression for 
cross-architecture emulation, but I don't really have the time to get a 
lot of the new features working for the cross-architecture case.  I 
would expect, though, that if these things were merged, it would make it 
relatively easy for someone else to do that though.

Is this a reasonable merge strategy?  We won't introduce regressions but 
I can't guarantee these new things will work cross-architecture.

Regards,

Anthony Liguori
